| Abstract: | In this paper the production methods of neodymium and neodymium-rich alloy were briefly reviewed, and the basic principle of winning Nd-Fe alloy by molten salt electrolysis with consumable iron cathode in NdCl_3-KCl melts as well as the selection of technological parameters of this process were discussed in detail. High-quality Nd-Fe alloy containing only 13% Fe was prepared in laboratory. The current efficiency of alloy reached as high as 69%. The recovery of neodymium was always more than 90%. The experimental results showed that the present process for electrowinning Nd-Fe alloy is effective, economical, simple and convenient. |
